Acrodermatitis enteropathica is a rare hereditary or acquired disorder of hypozincemia. It is characterized by acral and periorificial dermatitis, alopecia, diarrhea and growth retardation. Anorexia nervosa is characterized by low body weight, body image distortion with an obsessive fear and is also associated with various cutaneous findings including acrodermatitis enteropathica. We report a 37-year-old female with acrodermatitis enteropathica showing acquired zinc deficiency with anorexia nervosa.

Background: Phytoclear-EL1, an extract from Euphorbia lathyris seeds, has a whitening effect due to inhibition of tyrosinase activity. Objective: The purpose of this study was to investigate the inhibitory effect of phytoclear-EL1 on melanogenesis. Methods: Cultured B-16 melanoma cells and 30 human volunteers were used for in vitro and in vivo studies, respectively. Phytoclear-EL1 was added to the cultured B-16 melanoma cells, and applied to UVB-induced hyperpigmented lesions of human volunteers twice daily for 7 weeks. Changes in the number of B-16 melanoma cells, as well as changes in morphology, melanin content, and tyrosinase activity, were measured and then compared with the normal control and the 10 −3 M arbutin groups. Also, the effect of phytoclear-EL1 on UVB-induced hyperpigmented lesions was examined through subjective and objective measurements. Results: In the in vitro study (p＜0.05), the number, melanin content, and tyrosinase activity of cultured B-16 melanoma cells were decreased in the 5μg/ml phytoclear-EL1 group compared to the control group. On objective assessment with a chromameter, the 0.2% phytoclear-EL1 group had a larger difference in the mean L values before and 7 weeks after applying phytoclear-EL1 as compared to the other groups. On subjective assessment by both the researchers and subjects 7 weeks after applying experimental materials, the 0.2% phytoclear-EL1 group and positive control (3% arbutin) had higher scores than the placebo groups. These results demonstrated that phytoclear-EL1 in vivo and in vitro had an inhibitory effect on melano-

Post-steroid panniculitis is known to be very rare and most of the reported cases have been in children after corticosteroid therapy. We present a case of post-steroid panniculitis occurring in a 60-year-old man after massive, long-term administration of corticosteroids for acute exacerbation of chronic obstructive pulmonary disease (COPD). Histopathological examination of a nodule revealed a patchy area of fat necrosis, several multinucleated giant cells containing needle-shaped clefts. The lesions subsided completely in approximately 12 weeks without any treatment. We suggest that post-steroid panniculitis is not confined to childhood but also occurs in adulthood.
